I have a GIS oracle database and I am needing to reference in a SSIS dataflow task. Ideally I would normally do something like this (which works perfectly in Oracle SQL Developer):
execute sde.version_util.set_current_version('SAFE.mvedits')
SELECT CAD_EVENTID
FROM SAFE.INCIDENT_POINT_MV
however when I try to use that as the SQL command of my OLE DB Datasource it throws me an "Invalid SQL" error.
How do I set the SDE version in a SSIS dataflow task data source?
Knowing nothing of nothing on Oracle, what you might try is
In your Oracle Connection Manager, change the property RetainSameConnection to True. This means that all connections will Oracle will use the same thread.
Add an Execute SQL Task before your Data Flow that talks to Oracle. Use your query there to modify the current version thing. This setting should be persisted on the connection.
In your OLE DB Datasource, start with the SELECT statement.
You might need to set DelayValidation to true as well.
If that's not working, let me know and I'll see if I can come up with anything else.
As it turns out this is a shortfall of interacting with GIS Oracle databases through thirdparty applications. In my situation we addressed it by just bundling the change up in a stored procedure that lives on the oracle server and invoking that stored procedure from inside SSIS.

A user has been configured on Oracle. Via this user, I can create an ODBC connection and an OCI connection, and these both test fine in Win10. Using Alteryx with the ODBC and OCI connection, we try to write data to a new table.
The table is created and appears in PL/SQL with the expected column names. However, the rows are never written and the connection just hangs at this point.
What could be wrong? I am not an Oracle Admin
Based on comments you were expecting oracle to commit without executing "commit" command explicitly. It's not enabled by default in oracle so you have to turn it on.
It's not possible to turn this on for the database, but on client apps only.
E.g. "set autocommit on" command in SQL Plus.
So you need to check docs for the client application you're connected with (presumably Alteryx is the one). It might have such a feature.
I'm trying to export an Oracle DB using Oracle SQL Developer having tables, sequences, view, packages, etc. with dependencies on each other.
When I use Tools -> Database Export and select all DDL options, unfortunately the exported SQL file does not preserve the other that is some DB objects should be created before some other.
Is there a way to make the DB export utility preserve object dependencies/order? Or Is there any other tool do you use for this task?
Thank you
Normally expdp does a pretty good job. Problems arise when there are dependencies on objects/users that are not part of the dump. This is because the counter part, impdp, does not add grants on objects that are not created by impdp. I call that the 'not created by me syndrome' that impdp has.
If you have no external dependencies (external meaning to schema's that are not part of the dump), expdp/impdp do a good job for you. You might not be able to use it if you can not have access to the database server since expdp writes it's files on the database server.
If you happen to have access to a database server that is able to connect to the original database, you could pull the data over into your local database using a database link.
This came up once before: Use DataContext.CreateDatabase in SQL Azure
The answer accepted was "maybe it's not possible". Didn't seem like a full answer.
I have a set of classes fully defined and I am wanting to create a database on Azure for this. It's not working because the USE statement does not work: http://msdn.microsoft.com/en-us/library/azure/ee336288.aspx
So, the database gets created as blank, and internally Linq generates a USE statement to move to that database and start adding tables. This fails and it throws an exception.
So how can I create my database? Can I use Linq to add tables to an existing database? Can I enable USE on Azure somehow? Seems ridiculous this does not work.
After messing around for a while on this, I ended up creating the database against a local SQL Server instance. Then used SQL Server Management Studio -> Tasks -> Script Database, and turned on the export type to be Microsoft Azure. Then I had the script file needed to run on the Azure server. I'll leave the question open for a day or two because I am curious if this can work with Azure directly somehow. If I don't hear anything, I will close it.
The USE statement does not switch between databases in Azure SQL Database. You will have to connect to the database to create a table on that database.

I have a WCF service that uses Microsoft Enterprise Library Logging to log some messages to the Event Log. That works just fine.
The problem is that i want to log some messages to a table in an Oracle database. I am using the Entity Framework to communicate with that Oracle database.
The next step is a right click on the 'web.config' and choose the option 'Edit Enterprise Configuration'. I get the 'Enterprise Library Configuration' editor. In there i am trying to set the Logging Settings so that it also logs to the database, but when i add a database trace listener it´s asking me to fill in a procedure name. Do i have to add a procedure name to fill the table in Oracle? The msdn tells me to run the script that create an MSSQL database 'Logging' and some tables. But i don't have an MSSQL server, i have an Oracle server. And i don't want to use a seperate logging database, but save the logs to a single table.
Can anybody help me with this?
Kind regards
The Enterprise Library Database Trace Listener uses 2 stored procedures to write to the database: Add Category Procedure and Write To Log Procedure.
There is a SQL Server script to create the tables and stored procedures. This would have to be ported to Oracle.
Unfortunately, it looks like this does not work as easily as you would hope. See the blog post, Enterprise Library Logging to Oracle Database (this is based on EntLib 3, I believe) and the work item Cannot log to oracle Database using logging blocks for a description of some of the issues as well as some downloads to help.
i am newbie to oracle and i like to export database from remote database and import it on local machine. eOn both machines i have oracle 10.2.
I need to know how to export/import schema and data from oracle 10.2 using SQLDeveloper 3.0.0.4.
To export from remote database, i have used export Tool-> Database Export -> export wizard.
and at the end i have got only sql file with DDL and DML statements but somewhere in file it is written
"Cannot render Table DDL for object XXX.TABLE_NAME with DBMS_METADATA attempting internal generator error.
I have ignored previously mentioned message and tried to run those DDL and DML statements but all this ended up with errors.
Is it possible that all this tied with read-only database user? More over, i dont find any table under tables but also tables under other users in SqlDeveloper.
Thanks in advance
As a test, can you select one object in the tree, and navigate to the script panel? SQLDEV also uses DBMS_METADATA to generate those scripts.
Also, as a work-around, try using DataPump to export and import your data. It will be much more efficient for moving around larger schemas.
Your note about not seeing tables under indicates your schema doesn't actually own any tables. You may be working with synonyms that allow you to query objects as if they are in your account. You could be running into a privilege issue, but your error message doesn't indicate that. Error messages often come in bunches, and the very first one is usually the most important.
If you could try using the EXPORT feature say against a very simple schema like SCOTT as a test, this should indicate whether there is a problem with your account settings or with the software.
I'm not sure with SQL Developer 3.0 but with version 3.1 you can follow this:
SQL Developer 3.1 Data Pump Wizards (expdp, impdp)
